Is it possible to copy one or many users from one client to another? For example, copying client 911 to 610 without logging on to that client (610) and starting from scratch? I'm afraid this functionaly does not exist in SAP, yet. Hopefully they will provide that in a future release. Currently, you have to create the users manually. You can, of course, copy and paste parameters, profiles and roles (activity groups). For example: you can log on to both clients and edit the user in the source client via SU01 and copy all the roles. Then, create the user in other target client and paste them. If you were to copy all the users and their respective roles from one client into another, then you could use the copy profile SAP_USER.
